There are 2 ways you can go about this. But either way if you are going to do virtual reality its not going to be cheap. I would probably get new gear. But its a lot more expensive so do some research. 


1) cheaping out - requires research, you might not be able to do this. I would do some reading. Because CPU's that fit in that motherboard can far outperform the minimum i5-4790k.


This avoids having to replace the motherboard. I probably wouldn't pick this path but its quite possible it will work its worth looking into.


You have a sandy bridge motherboard Find out if your motherboard can take Ivy Bridge CPU's. If you can update the BIOS to do that then look around for a I7-3770K. Yes the 1070 will probably work fine in your board provided its PCI-E 3.0 compatible. This is the cheapest upgrade of the CPU because you wont need to replace the motherboard, and ram and CPU. Just the CPU. You will also need to check if anyone has used an Ivy bridge cpu with an Oculus rift or HTC vive. Ivy bridge is an intel 3rd gen processor. If the minimum spec for a rift is a generation 4 i5 then I would check this out, it might have particular cisc instruction sets you need in which case you will need to go with option 2. If it runs find on a grunty 3rd gen I7 processor then I would just do that. 


Run the Steam VR Test app:


2) Upgrading the whole pc internals.


I would probably look at the i5-6500k. The K means its overclockable. If not get the CPU @networkn recomended. And it means you can go with the H170 instead of a Z170 motherboard to save a few $.


You will need to buy a new motherboard. And will probably want to go with one with a Z170 chipset. You can go with an H170 chipset but if you do this dont get a 'K' version of a cpu its just a waste and you wont be able to overclock. I would go with a Z170 motherboard if you buy a 'k' cpu. 


You will need to replace your ram. Get 16GB you probably wont need more, although some people will disagree, get DDR4 its better, so check this on the lga1151 motherboards. Some still do DDR3.


Get a GTX1070 or GTX1080 the pascal ones in a few months after the supply issues are sorted out, and you can get a board partners one a bit cheaper than the founders edition. These are better for VR than a GTX 97x or GTX98x. As mentioned these wont be cheap. About $900~$1000 in NZ in a couple months for a 1070 and you might pick up a 1080 for about $1200~$1300.


The last thing you should check is that your current PSU can handle it. You might be fine here but I would check. And if its old or out of warranty I would look at replacing it. If you need to buy a replacement PSU, I would probably steer clear of the cheap stuff get something gold rated or better. The EVGA SupaNOVA comes with a 10 year warranty. So its a good product.


Also remember the HTC Vive is $799 USD or an Oclus Rift is $599 USD, so in NZ dollars thats a lot more than a straight exchange rate conversion.

Thanks for that, at this stage decided to get a 1070 in about a month or so, then upgrade CPU/Mobo/RAM a few more months after that.


Rift arrived two weeks ago, loving it. My specs can handle the more basic games fine but will need the upgrade for the more demanding titles.

Good to see there is another VR user here.


I've got the HTC Vive being driven off a asus 980 and i7-4790.


Bought it directly from HTC a month or two back and I love it.


The ability to walk around my study in the VR world is amazing.


Sword fighting the monsters of Vanishing Realms and resulted in the odd dent to the handset though.


Surprising how quickly small children settle into the game enviroment.

You might find this article interesting ... Then and Now: Almost 10 Years of Intel CPUs Compared


Also, this page compare gaming performance of Intel CPUs over the years... Gaming with the GeForce GTX 980


I find it surprising how well the i5 2500k and i7 2700k perform in relation to the latest CPUs - especially in gaming.


Then there is this article on Nvidia graphics cards over the years... Then and Now: 5 generations of Geforece Graphics Compared


There is a lot clearer improvement over time with GPUs.


It looks like you would definitely get a boost by upgrading your graphics card and not much of a difference from upgrading your CPU.

I'm going to be in NY just before Xmas.


Not sure I can really justify 980->1080 but if she gets lots of clothes, what do I get?
